Paramonohystera eurycephalus sp. nov. is characterized by relatively wide head diameter (33 μm in width), large cup-shaped buccal cavity; presence of numerous long cervical setae; amphidial fovea 18–20 μm in diameter; spicules slender, arcuate, 3.1–3.2 anal body diameter; gubernaculum tubular with a distal hook; five to six minute precloacal supplements. Steineria sinica sp. nov. is characterized by eight groups of three subcephalic setae at almost same level as cephalic setae; eight groups of two long cervical setae situated between subcephalic setae and amphidial fovea; amphidial fovea round, 35% of corresponding body diameter, about one head diameter from anterior end; spicules slender, cephalate proximally and taper distally; gubernaculum pipe-shaped with dorsocaudal apophysis; tail conico-cylindrical with three long terminal setae.     

Two new species of Pogonognathellus (Collembola: Tomoceridae) from China,with a discussion of East Asian species

Thirteen species of the genus Pogonognathellus Paclt, 1944 Paclt, J. 1944. Nomina nova in Collembola. Entomol Listy, 7: 92 [Google Scholar] have been reported worldwide, two from East Asia. Two new species of the genus from Jilin Province, northeast China are described here. Pogonognathellus heterochros sp. nov. is characterized by its unique body colour. Pogonognathellus mai sp. nov. is most similar to Pogonognathellus beckeri (Börner, 1909) but differs from it mainly in maxilla and tenaculum. A key to the East Asian species is provided, and the confusion among these species is discussed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:902CD044-0A58-4CCF-A1B1-449C9DE10938     

Two new free-living marine nematode species of Chromadoridae (Nematoda: Chromadorida) from the Yellow Sea,China

Two new species of free-living marine nematodes, Ptycholaimellus ocellatus sp. nov. and Prochromadorella gracilis sp. nov. from the Yellow Sea, China are described. Ptycholaimellus ocellatus sp. nov. is characterized by the presence of ocelli, an abruptly narrowing anterior cervical region, a cuticle with transverse rows of punctations, a lateral differentiation with two longitudinal rows of thick elongate dots, and voluminous ventral gland with a large ampulla. Prochromadorella gracila sp. nov. is characterized by the combination of lateral differentiations in the anterior pharyngeal region, a small conical stoma with outstretched teeth, slit-like amphidial fovea, and five pre-cloacal supplements.

A new species of the scorpionfly, Panorpa longihypovalva sp. nov., is described and illustrated from the Qinling‐Bashan Mountains, the dividing line between the Palearctic and the Oriental Regions in central China. The immature stages, including egg and larva, were obtained through rearing. Its biology and behaviour are briefly reported and illustrated.     

Two new species of Lauratonema (Nematoda: Lauratonematidae) from the intertidal zone of the East China Sea

Two new species of free-living marine nematodes of the genus Lauratonema Gerlach, 1953 from an intertidal sandy beach of the East China Sea are described and illustrated. Lauratonema macrostoma sp. nov. is characterized by a spacious buccal cavity, depth 2.1–2.3 times width; cup-shaped amphids; small blade-like spicules (14–16 µm long, 0.55–0.65 anal or cloacal body diameter [a.b.d.]) and unequal length of outer labial setae and cephalic setae (13–17 µm and 9–12 µm respectively). Lauratonema dongshanense sp. nov. can be distinguished by the small buccal cavity with a strong cuticularized transverse strip structure; cup-shaped amphids; small blade-like spicules (14–15 µm long, 0.58–0.67 a.b.d.), unequal length of outer labial setae and cephalic setae (8–10 µm and 5–7 µm respectively); the presence of a small precloacal papilla. A dichotomous key for the genus Lauratonema is given.

Two new species of the genus Sinella Brook, 1882 (Collembola: Entomobryidae) from East China

Two new species, Sinella hexaseta sp. nov. and Sinella pauciseta sp. nov., collected from East China, Anhui and Zhejiang provinces, respectively, were described. Both are easily discriminated from each other and all known Sinella species by their unique dorsocentral chaetotaxic patterns on Abd. IV. In S. pauciseta sp. nov., postlabial setae H_1–4 are ciliate, which are smooth in all other known species of the genus.     

A new damsel-dragonfly from the Mesozoic of China with a hook-like male anal angle (Odonata: Isophlebioptera: Campterophlebiidae)

A new genus and species of campterophlebiid dragonfly, Angustiphlebia mirabilis gen. nov. et sp. nov., is described from the Jiulongshan Formation in China. It has some remarkable venational structures, i.e. a hypertrophy of the male hind wing anal angle, a quite long gaff, and a secondary branch of the anal anterior near subdiscoidal cell in hind wing, supporting the hypothesis of a sister-group relationship with the genus Oreophlebia. These new data will help to solve the phylogenetic relationships within the Campterophlebiidae. http://www.zoobank.org/urn:lsid:zoobank.org:pub:16E602E6-3567-44D7-BF64-95A6597E55DE     

First record of the genus Koreanurina Najt and Weiner (Collembola: Neanuridae: Pseudachorutinae) from China,with description of two new species from Changbai mountain

The genus Koreanurina Najt and Weiner, 1992 is recorded for the first time from China. It is redefined and its similarity with the subfamily Caputanurininae is stressed. Two species are described from Changbai Mountain in North-East China: Koreanurina weinerae sp. nov. and K. alba sp. nov. The first species differs from the other species of the genus, mostly by its post-antennal organ located on the lateral edge of head (versus dorsolaterally), its central plate on head wider and the presence of only 1 + 1 chaetae on Th I (versus 2–3 + 2–3). K. alba sp. nov. differs from the other species of the genus mostly by the absence of body pigment, and the presence of only 1 + 1 chaetae posteriorly to the furcal rest (versus 2 + 2).

Three new species and one new record of the genus Doryphoribius Pilato, 1969 (Tardigrada: Eutardigrada: Hypsibiidae) from the Great Smoky Mountains National Park (Tennessee,USA)

Box jellyfishes (Cnidaria: Cubozoa) have a profound impact on human activities because of their highly potent venoms that may lead to severe envenomations in humans. Cubozoa is one of the smallest classes within Cnidaria with only some 50 described species in seven families. The literature on Cubozoa is scattered and oftentimes difficult to access. In particular, comprehensive treatments of Cubozoa that present a comparative overview of the group are either non-existent or largely outdated. Here we provide a synopsis of the carybdeid Cubozoa (Carybdeida) including an illustrated key to the families and genera of this order. Of particular interest is the family Carukiidae, which contains the species that was originally attributed with causing a severe envenomation syndrome called Irukandji syndrome. One new species of Carukiidae, Malo filipina sp. nov., is described, Morbakka virulenta is redescribed and a neotype is designated, and an unidentified species of Morbakka is recorded from the Philippines.     

Two new species of the genus Paracyatholaimus Micoletzky (Nematoda: Cyatholaimidae) from the Yellow Sea

Two new free-living marine nematode species of Paracyatholaimus Micoletzky, 1923 Paracyatholaimus qingdaoensis sp. nov. and Paracyatholaimus huanghaiensis sp. nov. from the Yellow Sea, China are described. Paracyatholaimus qingdaoensis sp. nov. is characterized by cylindrical body with conical tail; spicules reverse S-shaped, distally pointed; gubernaculum plate, with two cusps at distal end, parallel to the spicules; 10 thick setose precloacal supplements in a 5 + 5 arrangement, anterior group of five supplements located at a protuberance. Paracyatholaimus huanghaiensis sp. nov. is characterized by a cylindrical body with conic-cylindrical tail; slender spicules curved, distally pointed; gubernaculum handle-shaped, expanding distally to a plate, with some sawteeth at distal end; three papillose precloacal supplements, each papilla protruding conically with cuticularized narrow ducts. A key for identification of species of Paracyatholaimus is proposed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:0A8E40E5-AE7A-47DA-B755-61E1D088C1E9     

A new species of Friesea (Collembola: Neanuridae) from the Antarctic Continent

A new species of Friesea was found in East Antarctica and is described here as Friesea eureka sp. nov. This is the first new collembolan species to be described from the Antarctic continent in 30 years, even though ice-free areas have been intensively surveyed over that time. It brings to five the number of described species of the genus Friesea known from the Antarctic continent and Peninsula, so is the most speciose genus of Collembola in the region. However, one of these, F. grisea Schäffer, comprises a number of cryptic species of different molecular lineages. The new species is distinguished by having 4 + 4 ocelli plus 1 + 1 hardly visible, a very reduced furca, up to four or five faintly clavate tenent hairs, four anal spines and four spinose chaetae in adult. The restricted distribution of the species emphasises the importance of protecting ice-free areas on the continent as they often contain at least one locally endemic faunal species

Report on the Raphitomidae Bellardi, 1875 (Mollusca: Gastropoda: Conoidea) from the China Seas

Twenty-seven Raphitomidae species belonging to nine genera, are recorded from the China Seas, including two new species, which are described here: Asperdaphne paramoretonica sp. nov., Daphnella inangulata sp. nov. Eight species are recorded for the first time from the China Seas.     

A new species of Protocladorchis (Paramphistomidae,Dadaytrematinae) from Pangasius nasutus (Bleeker, 1863) in Thailand

Protocladorchis chinabutae sp. nov. from Pangasius nasutus in Thailand differs from Protocladorchis burmanicus mainly in the size, shape and position of the testes and from P. pangasii in body shape, egg size and the shape of the pharyngeal sacs. The genus has not previously been reported from Thailand.     

A new species of the genus Zhangixalus (Amphibia: Rhacophoridae) from Vietnam

ABSTRACT

A new rhacophorid species is described from Vietnam on the basis of nine specimens collected in Quan Ba District, Ha Giang Province, northeastern Vietnam. The new species is morphologically similar to Zhangixalus pinglongensis, Z. dorsoviridis, and Z. nigropunctatus, however, it differs from the latter by having the flank cream with large black blotches on axilla and groin. The genetic distance between the new species and Zhangixalus pinglongensis, Z. dorsoviridis and Z. nigropunctatus is >3.57% (16S mtDNA gene fragment). Zhangixalus jodiae sp. nov. can be distinguished from all other species of Zhangixalus and other small rhacophorid species from Southeast Asia by a combination of the following characters: size small (SVL 36.1–39.8 mm in males); head as long as wide; vomerine teeth present; dorsal surface of head and body green without spots; axilla cream with large black blotches, groin and front-rear parts of the thigh, ventral surface of tibia black with orange blotches; lower jaw region greyish, chest and belly cream.

A new nurse frog from Southwestern Amazonian highlands,with notes on the phylogenetic affinities of Allobates alessandroi (Aromobatidae)

ABSTRACT

Few studies have focused on the diverse fauna of southwestern Brazilian Amazonia. This region, spared from large-scale human occupation until the second half of the twentieth century, has been threatened by expanding agriculture, logging, and mining. Here, we describe a new nurse frog (Allobates, Aromobatidae) from the open highland habitats of Serra dos Pacaás Novos, one of the few large remnants of relatively intact native vegetation in the Brazilian state of Rondônia. The new species is diagnosed by its metallic orange dorsal colouration, weakly expanded discs on hands, and presence of two subarticular tubercles on Finger IV. A phylogenetic analysis based on DNA sequence data recovered the new species as more closely related to nurse frogs from the Madeira and Tapajós River basins; this pattern may reflect a history of dispersal uphill from a lowland ancestor. Our results also indicate that the generic assignment of Allobates alessandroi (Grant and Rodriguez, 2001), a high-elevation species from the Andes of Peru, needs to be reassessed; we discuss the phylogenetic affinities of this species based on morphological attributes.

Description of two new species of Zosime (Copepoda: Harpacticoida: Zosimeidae), including remarks on its phylogeny and distribution on the Great Meteor Seamount plateau (North-east Atlantic Ocean)

Quantitative sampling during the POS397 GroMet expedition in 2010 allowed analysis of the community structure of Zosimeidae on the Great Meteor Seamount (GMS) plateau. Twelve species of Zosime Boeck, 1873 were identified; 11 were recorded in the middle, nine in the northern, and 10 in the southern region. Similarity and diversity analyses showed no differences in community structure between these regions. The community seemed unaffected by geographical features; similarities between regions could reflect the uniform sediment structure and the complex water current system. Zosime can be characterised as monophyletic, due to the apomorphic one-segmented endopod of the mandible, armed with at most four setae. Two new species are described. Zosime carsteni sp. nov. (incrassata group) is defined by blunt spinules on the outer spines of exopods 1–3 of pereiopods 2–4 and the spinose nature of the innermost distal element of endopod 3 of pereiopods 1–4. Zosime eliasi sp. nov. (typica group) is defined by a flexible outer seta on the maxillipedal endopod. As both species bear an eight-segmented antennule (most plesiomorphic condition known so far), the recently erected anneae group is included into the typica group. An updated key of Zosime at the species level is given.

A new species of Munromyia Bezzi (Diptera: Tephritidae) reared from Chionanthus battiscombei (Oleaceae) in northern Kenya

Munromyia marsabitensis sp. nov. is described from the isolated mountains of Marsabit in northern Kenya. It can be distinguished from the two known congeners by the thoracic and abdominal colour patterns, structure of the male and female terminalia, and host plants. Larvae are seed predators, developing within the green, aborted fruits of Chionanthus battiscombei. Over 70% of sampled fruits (n?=?74) were infested with larvae, but nearly all of the individually infested fruits (96.1%) produced only one adult tephritid. Bactrocera biguttula, but not M. marsabitensis, was reared from ripe fruits of the same plant.     

A new pontoniine shrimp genus (Crustacea: Decapoda) from the Yemen,with a note on other species

An unusual new genus and species of coral inhabiting pontoniine shrimp from the Yemen is described and illustrated. The new shrimp is remarkable for its very small size and the unique form of its telson. Three other pontoniine shrimps are also reported from the Yemen for the first time, raising the number of such shrimp species known from southern Arabia to 18.
